Abstract: A method of disengaging an anti-backup pawl from a film winding thumbwheel to permit an unexposed filmstrip to be prewound from a film cartridge during original manufacture or recycling of a one-time-use camera has the steps of: depressing a movable free end of the anti-backup pawl to pivot the anti-backup pawl at a fulcrum support between the free end and a movable opposite end of the anti-backup pawl that engages the film winding thumbwheel, in order to disengage the opposite end from the film winding thumbwheel; and holding the free end depressed to maintain the opposite end disengaged from the film winding thumbwheel, in order to permit the film winding thumbwheel to be rotated in engagement with a film spool in the film cartridge when the unexposed filmstrip is prewound from the film cartridge.

Abstract: A water-resistant camera comprising a main body part having a rear back frame opening across which successive sections of a filmstrip are moved to be exposed, a rear cover part lighttightly covering the backframe opening, and a water-resistant casing part spaced opposite the rear cover part, is characterized in that the main body part has spacer projections separate from the backframe opening for abutting one side of the rear cover part which faces the backframe opening, to maintain a film clearance space between the backframe opening and the one cover part side for movement of successive sections of the filmstrip across the backframe opening, and the rear cover part has support projections aligned with the spacer projections, on another side of the rear cover part which faces the water-resistant casing part, whereby when water pressure tends to press the water-resistant casing part inwardly toward the rear cover part the support projections will cooperate with the spacer projections to prevent the water-resi

Abstract: A camera assembly comprises a plurality of encodement-on-film recording means adapted to receive electrical energy to provide various film encodements, an encodement-on-film selector movable to various selection positions to select one or more of the recording means to provide the film encodements, a flash charge storage capacitor, and a shutter-flash synch contact connected to the flash capacitor to enable the flash capacitor to supply electrical energy when a shutter blade impacts the synch contact. Respective ones of the recording means are coupled via the synch contact to the flash capacitor to receive electrical energy from the flash capacitor. The synch contact supports the selector for movement to its selection positions and is coupled to the selector to permit the selector to select one or more of the recording means to receive electrical energy from the flash capacitor. This arrangement provides a savings of parts desirable in a low cost camera.

Abstract: Optical film encoding apparatus comprising an LED with a pair of wire leads, and means for supporting the LED including its wire leads to precisely position the LED opposite a filmstrip to be optically encoded, is characterized in that the supporting means supports each one of the wire leads suitably bent at multiple angles to prevent stray ambient light from following the wire leads towards the filmstrip. Preferably, the supporting means includes a lead spreader which supports the wire leads bent at an initial one of the multiple angles closest to the LED in opposite directions to dynamically balance the deformation forces applied to the wire leads due to their being bent. This is done to prevent the deformation forces from otherwise tending to shift the LED from being precisely positioned relative to the filmstrip.

Abstract: An apparatus for coupling which includes first and second shafts, each having an axis. The axes are disposed in generally coaxial relationship. The apparatus includes coupling having first and second members for coupling the first shaft to the second shaft to allow transmission of rotational movement from one of said shafts to the other of said shafts upon rotation of the one shaft. The first and second members have a configuration which allows transmission of rotational movement from one shaft to the other shaft in a first direction of rotational movement and not allowing transmission of rotational movement from one shaft to another shaft in a second direction of rotational movement. The first member is mounted on the first shaft so as to allow movement on the first shaft in a direction that is perpendicular to the axis of the first shaft.

Abstract: A zoom lens includes a lens group mounted in a cam barrel mechanism which includes a fixed barrel with a cam barrel rotationally mounted thereon. The lens group has a pin which projects through an axially extending clearance slot in the fixed barrel and a compliant feature on the pin removes the clearance between the pin and the slanted cam slot in the cam barrel so that as the cam barrel is rotated the lens group translates axially within the fixed barrel. The fixed barrel has an endcap with array of centering orifices mounted thereon and a beveled surface which is engaged by an outboard edge of the cam barrel. The cam barrel is urged against the endcap by a wave washer disposed between the cam barrel and a base. Radially disposed with respect to the cam barrel are a pair of spaced lugs and a bowed sheet spring which engages the cam barrel to urge the cam barrel against the lugs. The wave washer and bowed sheet spring positively locate the cam barrel with zero clearance.
